Abstract
OBJECTIVE:To explore long-term following-up clinical effects of lateral closed high tibial osteotomy for the treatment of knee osteoarthritis.
METHODS:Twenty patients with medial unicompartmental knee osteoarthritis were treated with lateral closed high tibial osteotomy and screw fixation from June 2005 to December 2015. Among them, including 17 females and 3 males, aged from 43 to 76 years old with an average of (57.80±8.05) years old. VAS score and KSS score were applied to evaluate recovery degree of pain and function before operation and after operation at 1, 5 and 10 years, and postoperative complications were observed.
RESULTS:Sixteen patients were followed-up, the time ranged from 9 to 11(10.0±0.8) years, 4 patients were loss to follow-up. Preoperative VAS score was 7.88±1.15 and decreased to 3.19±0.91, 3.44±0.96, 3.69±1.20 at 1, 5 and 10 years after operation, and there were statistical differences in VAS score between before and after operation at different time points (P<0.05). Clinical score of KSS increased from 61.94±5.74 before opertaion to 75.50±4.62, 80.13±3.97, 77.38±6.40 at 1, 5 and 10 years after operation, and there were statistical differences in clinical score of KSS between before and after operation at different time points(P<0.05); functional score of KSS increased from 62.81±13.03 before operation to 77.50±8.56, 81.88±6.55, 76.88±10.78, and there were statistical differences in functional score of KSS between before and after operation at different time points(P<0.05). All incisions healed well without complications such as fibula nerve injury and fracture nonunion.
CONCLUSIONS:Lateral closed high tibial osteotomy and screw fixation for knee osteoarthritis could receive good clinical results, stop and delay progress of knee osteoarthritis, and long-term following-up could achieve the same effect as total knee arthroplasty.
